Temporal variations in rainfall patterns in Kilembe, Uganda

Abstract

This study investigated rainfall variabilities in Kilembe. Secondary (monthly rainfall) data for the study were obtained from the Uganda National Meteorological Authority in Kampala, Uganda, for the period 1986–2016. To determine the temporal variation of rainfall, a Mann–Kendall method and Sen's slope estimator test were used. The results showed that March, April, May, October, and November represented the smallest coefficient of variation indicating modest variability of rainfall in these months, whereas June and July had the largest coefficient of variation. The month of July recorded an overall lowest average rainfall and a decreasing trend in rainfall. The study further revealed a historical general upward trend in rainfall between 1986 and 2016 in Kilembe. The trend in the monthly and annual rainfall is partly attributed to the Intertropical Convergence Zone, influx of moisture from Congo Forest, and climate change. The area recorded also two peaks of rainfall in the year, one in April and another in September, revealing a bimodal pattern of rainfall. The findings indicate that the government should adopt policy measures in the form of an adaptive strategy in order to save the people in the impacted areas.

Analysing drivers of community vulnerability to flood hazards in Kasese Municipality, Uganda

“…Age, gender, poverty and settlement in floodplains also affected the vulnerability of communities and individuals to floods (Mucherera and Mavhura, 2020). Bearing in mind the aforementioned literature, with the increasing trend in rainfall (Tibara et al, 2021a) and increasing frequency and magnitude of flash floods in the area (Jacobs et al, 2020;KDLG, 2020;Tibara et al, 2021b) with consequent damages, this research focused on analysing the drives of community vulnerability to flood hazards in Kasese Municipality.…”

Vulnerability assessment to flood hazards of households in flood‐prone areas of Kasese District, Western Uganda

“…Like much of the world, floods are common in Uganda (Ogwang et al, 2012; Tibara et al, 2021a). Besides causing death, floods destroy public health facilities, schools, and various infrastructures among others (Department of Disaster Preparedness and Management [DDPM] & Office of the Prime Minister [OPM], 2011).…”

Drought assessment and rainfall trend analysis in southwestern Nigeria

“…In recent times, several studies globally (Fetene et al, 2019;Malik et al, 2019;Rao et al, 2020;Meng et al, 2020;Bayable et al, 2021;Tibara et al, 2021) have assessed rainfall patterns in light rainfall pattern in rapidly urbanizing cities. There is also the need to incorporate climate-related adaptive strategies in existing water management policies.…”

“…Adeola et al (2021) asserted that rainfall patterns not only vary in amount from year, season, or month to another but may show a downward or upward trend over a given period. In comparing the highly variable nature of the rainfall in the tropics, with the relatively stable pattern of the temperature, rainfall appears to have more relevance as the major component in the study of climate (Gbuyiro et al, 2002; Tibara et al, 2021). In any agroecological zone anywhere in the world, rainfall is a major determinant of agriculture production (Meng et al, 2020 ).…”
